Replacing the detector leak sensor

Replacing the detector leak sensor
Topic LCI-USG-0177, Last Updated 11/08/2024

A leak sensor in the drip tray continuously monitors the detector for leaks.

Warning: To avoid personal contamination with biologically hazardous or toxic compounds, wear clean, chemical-resistant, powder-free gloves when performing this procedure.

The detector's leak sensor stops system flow when it detects accumulated, leaked liquid in its reservoir. When the sensor detects a leak, the system's touchscreen displays an alarm message.

Required tools and materials

  • Chemical-resistant, powder-free gloves
  • Replacement leak sensor

To replace the detector's leak sensor:

  1. Open the detector's door, gently pulling its right-hand edge toward you.
  2. Remove the old leak sensor:
    1. To detach the leak sensor connector from the front of the instrument, press down on the release tab.
      Note: The following figure is for representation only. Your hardware may differ slightly from that shown.

    2. To remove the leak sensor from the reservoir, grasp it by the serrations around its top and pull upward on it (see Figure "Installed leak sensor, rear view").
  3. Install the new leak sensor:
    1. Holding the leak sensor by its serrations, align its T-bar with the slot in the side of the reservoir and slide it into place (see Figure "Installed leak sensor, rear view").
